Equinoxes occur twice a year, around March 21 and September 23, when day and night are approximately equal in length due to the Earth's tilt being perpendicular to the Sun's rays. During these times, the Sun crosses the celestial equator, marking the transition between seasons: spring in the northern hemisphere and autumn in the Southern Hemisphere for the March equinox, and vice versa for the September equinox. Additionally, equinoxes signify a moment when the Earth's axial tilt is not directed toward or away from the Sun.
